Had I known they were like this, I would never have bought them! I would buy with a dust collector on a stick. This is easier to roll on the floor. Would like to return. But I don't know how. Its pros: Beautiful. A brush with a motor is a plus - without it I would not out ANYTHING! The dust box opens really super fast and convenient! Backlight (although it is also poorly located! ). It is convenient to collect crumbs from the sofa and bed. (Probably this is the only fat plus) Its cons: Heavy. The hand "falls off" straight, tired. Often you have to change hands. Weak. I read a bunch of reviews. Chose. But I did not expect HOW weak! But well done brush! Spins and collects. Another Disadvantage: Bulky main nozzle with LED bulbs. For what? 4. Illumination is poorly located, hard to see. Closer to the middle of the Nudo was to place these headlights. The battery can't be charged while shooting. I took it precisely because of this, in order to charge without the whole instruction. Written removable, but only for replacement with another.
